Answer: Option (b) is the correct answer.

Explanation:

When a substance resists or does not allow any flow of electric current through it then it is known as an insulator.

For example, rubber, glass, paper etc are all insulators.

A conductor is a substance that allows easy passage of electric current through it.

A radiator is defined as the substance which emits radiations to transfer heat energy for heating and warming purpose.

A solar collector collects radiations that are passed from the Sun.

Thus, we can conclude that an insulator is a material that reduces the flow of heat by conduction, convection, and radiation.

A person throws a ball straight up. He releases the ball at a height of 1.75 m above the ground and with a velocity of 12.0 m/s.

Lyrx [107]

Answer:

a) 1.22 s

b) 9.089 m

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 9.81 m/s²

$v=u+at\\\Rightarrow t=\frac{v-u}{a}\\\Rightarrow t=\frac{0-12}{-9.81}\\\Rightarrow t=1.22\ s$

Time taken by the ball to reach the highest point is 1.22 seconds

$s=ut+\frac{1}{2}at^2\\\Rightarrow s=12\times 1.22+\frac{1}{2}\times -9.81\times 1.22^2\\\Rightarrow s=7.339\ m$

The maximum height the ball will reach above the ground is 1.75+7.339 = 9.089 m

Does latitude has an effect on weight? PLEASE HELP!

kotegsom [21]

Answer:

yes

it does you weigh less on the equator than at the North or South Pole, but the difference is small. Note that your body itself does not change. Rather it is the force of gravity and other forces that change as you approach the poles. These forces change right back when you return to your original latitude.
